JULIUS SOMBART, OF BOONVILLE, MISSOURI.

FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 336,496, dated February16, 1886.

A pplication filed November 20, 1885. Serial No. 183,419. (No model.)

To all whom it may concern.-

Be it known that l, J ULIUs SOMBART, a citizen of the United States,residing at Boonville, in the county of Cooper and State of Missouri,have invented certain new and use ful Improvements in Feed-Regulators,of which the following is a full,clear,and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, in Which- Figure 1 represents a sectional View of afeed-hopper with my improvements attached. Fig. 2 is a front elevationof the same.

My invent-ion relates to a feeding device or hopper designed especiallyfor feeding grain or granular substances to grain-crushing mills,grinding-rollers, purifiers, or other grinding and dressing machinerywhere continuous and regular feeding is required; and my inventionconsists in the construction and combination of devices, which I shallhereinafter fully describe, and specifically point out in the claims.

In the drawings, A represents the ordinary feed-roll, which operates inthe dischargemouth of the hopper 13, arranged above said roll, and maybe of any desired form and size. WVithin the hopper,and forming thefront wall of its throat,is a vibrating feed-board,O,which is suspendedfrom the top of said hopper by suitable straps, D, provided wit-helongated slots to and set-screws b, whereby said feedboard is renderedcapable of vertical adj ustment to accommodate itself to the differentkindsofgrain. Passinglongitudinallythrough the hopper and in front ofthe feed-board is a shaft, E, upon which are mounted two down- Iwardly-projecting arms, F, the lower ends of which are adapted to bearagainst the feed board nearitsextremelower edge. Upon one end of thisshaft E is rigidly secured an arm, G, having a weight, H, adjustablymounted thereon, and serving as a counter-balance to regulate thedischarge from the hopper. Setscrews d pass through the lower end of thearms F and bear upon the front of the feedboard, and afford a minuteadjustment of the .latter with relation to the discharge.

The operation of the device is as follows: The stock is fed into thefeeding-hopper B. The opening of the throat at the base of the hopper isregulated and adjusted as desired by means of the weighted arm to feedthe stock, as required. Should the stock be fed into the hopper fasterthan it is being fed over the feed-roll A as the device is adjusted,theaccumulation of stock inthe hopper will speedily overcome the resistanceof the weight of the arm and cause the feed-board to yield, thus openingthe throat wider,feeding out the stock over the feed-roll more rapidly,and preventing the clogging of the hopper; but as soon as this is doneand the accumulation of stock in the hopper is relieved the weighted armand arms F'canse the board to resume the position to which it wasadjusted, closing throat again to the position to which it wasregulated.

Having thus described myinvention,what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a feed-roll, a stationary liopper,andadjustable feed-board, the straps and set-screws, of a longitudinalshaft, E, suitable arms mounted upon the shaft with their lower endsbearing against the feedboard,and a counter-balance for regulating thedischarge from the hopper, substantially as herein described.

2. An improved feeding device comprising a stationary hopper, afeed-roll, a feed-board suspended within the hopper and forming thefront wall of its throat, a longitudinal shaft, E, suitable arms, F,mounted upon the shaft and bearing against the lower part of thefeedboard, adjusting-screws d, an arm, G, secured to the shaft, and aweight movable upon said arm, substantially as herein described.

JULIUS SOMBART.
